Answer:

  B. 3x−y=36

Step-by-step explanation:

Multiplying the equation by 3 and subtracting the y-term gives you the desired form.

  x = 1/3·y +12

  3x = y + 36 . . . . . multiply by 3

  3x -y = 36 . . . . . . subtract y to get standard form

_____

Standard form has ...

  • only variable terms on the left side
  • a positive leading coefficient
  • only a constant on the right side
  • all coefficients mutually prime, integers where possible
  • variables in lexicographical order (optional, I'd say)
